bflatasticandClaude Opus 5.5 262caec2d6 Fix #505: Illustrator EPS type with drop shadows and glows opens as vectors
Text effects from stock sites are Illustrator EPS with live type whose
appearance (several fills and strokes, offset paths, drop shadows, glows) is
flattened into many small images and clipped type. Made here with
Illustrator 2026 (graphic styles and live effects on type, live and
outlined, formats 2026, CS6, 10 and 8), every one fell back to its preview:

- Illustrator's procsets keep their own graphics-state stack in a
  dictionary, count each `save` in it and raise `limitcheck` at 64, relying
  on `restore` to put the count back. `restore` didn't undo dictionary
  changes, so a file with more than 64 images (each drawn in a save)
  stopped. Now `restore` puts dictionaries back as they were at the `save`,
  as restoring virtual memory does: while a save is open, `def`, `store`,
  `put`, `undef` and dictionary `copy` keep the old value in a journal
  (counted against the memory budget), undone newest first. A save that was
  restored already (or through an outer one) can't be restored again
  (`invalidrestore`).
- The Illustrator 8 format's pattern fills divide by the font cache's
  largest glyph (`cachestatus`), which was 0: it now reports a printer's
  sizes.
- Type in Illustrator's reencoded font copies (`/Impact*1`) was set in the
  fallback font: the `*1` suffix is dropped when the family is looked up.

The images of those effects also came in banded on main; that is #498's
fix, which this builds on.

Tests: 100 saves counted in a dictionary and restored, every dictionary
change undone, saves restored twice, `cachestatus`, reencoded font names.
The import fuzz vocabulary has saves and restores around dictionary
changes. The generated files (not committed) now open with no warnings and
look like their previews; the Illustrator 8-format ones draw what their
PostScript holds (that format writes effects as opaque rasters).
